started to implement median
implemented remedian as a streaming approximate of actual median, seems it works, but it needs an actual test on a large dataset.
I tested this on kdd99 dataset and fixed merge
cleanup in SummaryTest
eliminated star import
Fixed conflicts introduced by merge upstream
removed currently obsolete DiscretizeCommand
Merge remote-tracking branch 'origin/master'
added secondary sort while creating a weighted list
initial effort for supporting quartiles
added quartiles to summary statistics, but this needs a test on a "large" data set.
reverted accidentally modified s.json file
revert completed
reformatted style
Merge pull request #19 from gcapan/median
